[0002] PICC is a kind of intravenous infusion channel. The PICC tube can be implanted in the heart, which is conducive to intravenous nutrition and clinical medication. It is mainly used for patients in the oncology department to avoid irritation to the surrounding blood vessels and to avoid repeated puncture of the surrounding blood vessels. After the actual PICC catheterization and puncture, it is usually necessary to continue to stop bleeding for six to eight hours.
[0003] The existing PICC hemostatic compressor is mostly fixed with Velcro straps. During the fixation process, the nurse needs to hold the hemostatic compressor with one hand to stop the bleeding and use the other hand to fix the strap, which is more laborious.

At this time, the position of the compressor needs to be fine-tuned. After the existing compressor is firmly fixed, the adjustment operation is more laborious. At the same time, the compression strength of the existing equipment is relatively fixed. As the blood is gradually stopped over time, the compression strength can be appropriately reduced.

[0024] The adjustment mechanism 6 includes a fixing ring 35 fixedly mounted on the bottom of the body 1, and four groups of threaded rods 36 are evenly arranged on the fixing ring 35. The four groups of threaded rods 36 respectively penetrate the side surfaces of the fixing ring 35 and are threadedly connected to the fixing ring 35. A pushing member 37 for controlling the device box 7 to adjust the horizontal position is provided on the threaded rod 36. The pushing member 37 includes a fixing tube 38 fixedly mounted on one end of the threaded rod 36. Four groups of guide grooves 39 are evenly opened on the side surface of the device box 7. A guide block 40 is slidably connected in the guide groove 39. The inner wall of the guide block 40 is movably sleeved with the outer wall of the fixing tube 38. A third spring 41 is fixedly connected to the guide block 40, and one end of the third spring 41 slides against one end of the threaded rod 36.
[0025] Working principle: when in use, first put the bandage 2 and the body 1 as a whole onto the patient's arm. When stopping bleeding, directly hold the body 1 with one hand to press the pressing block 4 to the position where compression is required to stop bleeding, and rotate the rotating tube 12 with the other hand. The rotating tube 12 drives the bevel gear ring 30 to rotate, and the bevel gear ring 30 drives the bevel gear 31 to make the second worm 32 rotate, thereby driving the second worm gear 34 to drive the connecting shaft 33 to rotate, and the connecting shaft 33 drives the first worm 28 at both ends to rotate, and the first worm 28 drives the corresponding first worm gear 27 and the winding shaft 26 to rotate, so that the two ends of the bandage 2 are gradually wound onto the winding shaft 26, so that the bandage 2 can bind the arm tightly and complete the fixed compression of the body 1 and the pressing block 4. At the same time, because the worm will automatically limit the worm wheel, it is avoided that the bandage 2 drives the winding shaft 26 to rotate in the opposite direction and loosens during use. The rotating tube 12 can be loosened at any position to complete the self-limiting of the two ends of the bandage, and the operation is more convenient and efficient.
[0026] When the strap 2 is fixed, it is possible to observe whether the compression position and the position of the pressing block 4 are appropriate through the entire body of the transparent material, and by rotating the threaded rods 36 around, when the threaded rods 36 are close to the device box 7, the third spring 41 at this position can be compressed, thereby increasing the thrust of the device box 7 to the other side, pushing the device box 7 as a whole to drive the pressing block 4 to slide to the other side, and by rotating and adjusting the four groups of threaded rods 36 around, the pressing block 4 can be fine-tuned to the desired position. During the adjustment process, the guide block 40 will slide in the guide groove 39, thereby realizing the limit guide function and ensuring that the top surface of the device box 7 is always in contact with the bottom surface of the body 1.
[0027] By pressing the control block 18, the gas in the rotating tube 12 can be squeezed through the connecting hole 13 and the one-way exhaust valve 22 to be transported to the device groove 9 at the bottom, and the air pressure above the push plate 14 increases, so that the push plate 14 moves downward to compress the first spring 15, and the tension spring 16 is stretched. After the first spring 15 is compressed, the downward thrust of the pressing block 4 can be increased to enhance the strength of the compression hemostasis. Then, the control block 18 is released, and the control block 18 moves upward and resets under the push of the second spring 19, and the external gas is transported to the rotating tube 12 through the air inlet hole 20 and the one-way air inlet valve 21.
[0028] It is worth noting that the gas in the device slot 9 will be slowly discharged to the outside through the exhaust hose 24 and the control valve 25, thereby gradually reducing the air pressure intensity in the device slot 9. Under the pull of the tension spring 16, the push plate 14 and the pressing block 4 gradually move upward to reduce the downward pressure. The exhaust rate of the exhaust hose 24 can be controlled by adjusting the control valve 25, so that the compression intensity of the pressing block 4 can be linearly and slowly reduced, avoiding the situation where long-term high-intensity compression affects the patient's comfort after hemostasis is completed. When the air pressure value in the device slot 9 is close to the external air pressure, the tension spring 16 and the first spring 15 are reset. After that, the pressure of the pressing block 4 on the body is relatively stable and comfortable. When the patient has bleeding during use, he only needs to press the control block 18 and release it to apply a certain compression intensity to the compression point again to achieve the hemostasis function. The operation is convenient and there is no need to panic. The control of the compression intensity is more precise and flexible, and there will be no situation where the patient's operation causes the compression intensity to be too large, too small or cumbersome.
[0029] During the process of the device box 7 being pushed and adjusted by the threaded rod 36, the top of the connecting hole 13 can always be connected with the bottom of the rotating tube 12, ensuring that the control block 18 can always transport the internal gas to the device groove 9 during the pressing process. At the same time, since the exhaust hose 24 is a hose structure, the two ends of the exhaust hose 24 can always be connected with the device groove 9 and the outside world respectively during the adjustment of the device box 7 and the pressing of the control block 18. The bottom end of the second spring 19 is fixedly connected to the inner wall of the body 1, so that the second spring 19 and the control block 18 will not be driven to rotate synchronously during the rotation of the rotating tube 12.
[0030] When it is necessary to loosen, hold the body 1 with one hand and use the other hand to reversely rotate the rotating tube 12, so that the bevel gear ring 30, bevel gear 31, second worm 32, second worm wheel 34, connecting shaft 33, first worm 28, first worm wheel 27 and winding shaft 26 can be driven to reversely rotate together, loosen the two ends of the strap 2, and then remove the body 1 and the strap 2 from the patient's arm together. The operation is simple and convenient.
[0031] The device has a simple and stable structure, is convenient and efficient to operate, and can flexibly adjust and control the bandage 2 while ensuring stable compression of the hemostasis position, thereby improving flexibility during use and facilitating independent operation by nursing staff.
